Product Detail

Product Tags


1. This charge controller is its ability to automatically identify the system voltage level. This means that the controller will be compatible with a wide range of solar panels and battery systems, allowing for greater flexibility and ease of use.
2. The Automatic Temperature Compensation feature ensures that the controller is able to adjust its charging parameters based on the temperature of the battery system, resulting in optimal performance even in extreme weather conditions.
3. The charge-discharge control parameters are fully adjustable, allowing you to customize the charging and discharging process to suit your specific requirements. This enables you to maximize the lifespan of your battery system and maintain optimal performance.
4. The Battery Low Voltage Disconnection (LVD) feature protects your battery system from damage due to over-discharging, while the overcurrent protection provides an extra layer of safety and ensures that your system is protected from electrical surges and overloads.
5. The Battery reverse connection protection and overcurrent protection features add yet another layer of safety and ensure that your system is protected from damage due to accidental mistakes or electrical faults.
6. Four-stage PWM charging: strong charging, lifting, floating charging, balance;
7. Lithium battery, colloidal, open and user mode four types of battery charging procedures are optional.
8. The use of liquid crystal display screen design, dynamic display equipment running data and working state.
9. With real-time electricity statistics function.
10. With battery temperature compensation function.
